Installation (from the manual)
Clearances and orientation
| Mounting methods and clamp zones | Use the bracket mounting screws (1.8 cm), anti-slip washers, and nuts to attach the angle adjustment plate and U-shaped bracket to the solar panel.; Select the optimal alignment hole for maximum sunlight exposure. Insert the angle fixing screw (1.5 cm) with an anti-slip washer, and secure it loosely with a wing nut.; If permanent mounting is required, use the provided self-tapping screws and expansion anchors to securely fix the bracket and solar panel assembly to your selected surface.[3] |
